We know a lot of theology; we have plenty of Catechisms. But do we know the mystery that is God? Do we know God personally in our hearts?
When questioned we speak or teach. We tend to rely on pedagogy rather than mystagogy.
Interestingly Jesus was not like that. When asked a question He never answered, He told a story. He told a parable. There is something about the parable that is marvelous. It is not just that it is a great and memorable way of teaching. It is more that it is a great act of confidence in the listener.
And remember the people who were asking Jesus questions were the religiously ignorant of His time, the sinners, the “lapsed Jews.” But Jesus did not feel it necessary to give them basic remedial instruction. He told them a story trusting that they had enough in their hearts to understand. He shared the mystery in His heart confident that they would recognize the truth of what He was saying because of the mystery in their heart. One might understand more than another, and another might only understand it fully years later, but they were talking at the level of mystery.
And they said of Jesus that He spoke with authority. Not because of His degrees, but because they knew what He said was profoundly true and life giving.
We need to learn to be like Jesus, to know deeply our own spiritual experience and then share our stories vulnerably and hopefully. Mission is an encounter with mystery and an exchange of mysteries.
